Aluminum Side Clamps for Mounting Housings

Thorlabs’ Customizable Electronics Housings are empty enclosures that enable the user to create custom electrical circuits, such as filters, voltage dividers, or impedance matchers. We offer these housings in two types. The smaller ET1 tube housing has a male BNC connector on one side and a female BNC connector on the other side. This in-line feedthrough housing is ideal for simple circuits made from a small number of standard electronic components or more complex circuits built with surface-mounted elements on a small printed circuit board (PCB). For circuits that require more space, the extruded electronics enclosures are ideal. These housings are slotted inside to accept printed circuit boards and are offered with blank end plates, female BNC connectors, or female SMA connectors. Several sizes are available; for detailed dimensions of the enclosures, please click on either the red Docs icons () or the blue icons () below.

Extra end plates and screws are available for many of the housings sold below. The end plates are blank or have female BNC or female SMA connectors. Aluminum side clamps are available as additional mounting options for the housings. The clamps have a #8 (M4) counterbore, which allows them to be mounted to a Ø1/2" post or other surface with an 8-32 (M4) tap. Alternatively, double-sided plastic clamps are available to mount a housing on top of another housing for a secure, compact setup.

Can you please confirm that the housings are electrically isolated from the outer conductor on the BNC output and input ? I'm concerned about pick-up from eg power supplies.
This question applies to all the filters Thorlabs are marketing, as well as the custom housing.
I'm failrly confident your answer is "YES", but I just want to confirm. Thank you.

Hello, thank you for contacting Thorlabs. The BNC case is directly and electrically connected to the body housing.

The recent introduction of your side clamps for your housings prompts me to suggest a housing accepting a standard arduino uno board and some side clamps which could fit your 30mm and 60mm cage system. Arduino is likely used by some of your customers alongside Thorlabs opto-mechanical elements (I am one of them), and a dedicated housing with cage clamps would be much welcome.

Hello, thank you for contacting Thorlabs. I have posted this feedback in our internal engineering forum.

Empty In-Line BNC Feedthrough Housing

Click to EnlargeThe ET1 housing is shown here with its outer shell removed (top). A blank label is included on the back side (bottom).

Ø0.63" × 2.61" In-Line BNC Feedthrough Housing

Compatible with Off-the-Shelf Electronic Elements

Accepts 10 mm x 15 mm PCB

Male and Female BNC Connectors

Blank Area to Label Custom Circuits

The ET1 tube housing is an in-line (feedthrough) BNC structure with a male BNC connector on one side and a female BNC connector on the other side (as shown in the image to the right). The 2-56 screw in the base provides a convenient connection to ground, and the compact design can easily house a small number of standard electronic elements (e.g., resistors, capacitors, etc.). The Application Idea at the top of the page shows the ET1 with a simple RC filter using standard circuit elements.

The ET1 electronic housing can hold a small (10 mm × 15 mm) form factor PCB that, using surface mounted elements, allows for the inclusion of many electronic elements. For example, Thorlabs' low- and high-pass filters (which were the basis for the ET1) house 5th and 6th order elliptical filters composed of anywhere from 8 to 15 electronic elements. The back side of the enclosure includes a blank label for identifying custom circuits. For detailed dimensions, click on the Docs icon () below.

These Extruded Electronics Housings are empty 1.00" x 1.25" x 2.51" enclosures with nickel-plated ends. The EEA14 has two female BNC connectors and the EEA17 has two female SMA connectors. The housings have slots inside to accept a PCB with a thickness between 0.060" and 0.070". See the table below for compatible PCB sizes for the enclosures. For detailed dimensions of each enclosure, click on the blue icon () in the table. These enclosures are ideal for housing a wide variety of electronic devices that can be built with surface-mounted elements, such as Thorlabs' EEAPCB1 Customizable Printed Circuit Board (shown in the image to the right), which gives users the ability to create their own RCL circuits.

The end plates of these housings are easily removable and are held in place with 4-40 round-head Phillips screws. The front side of the enclosures includes a blank label for identifying custom circuits. Note that these housings are made from extruded bar stock, and as such, some minor cosmetic defects in the finished products are to be expected.

These extruded electronics housings are empty enclosures with nickel-plated ends. For detailed dimensions of each enclosure, click on the blue icon () in the table below. The housings have slots inside to accept a PCB with thickness between 0.060" and 0.065". See the table below for compatible PCB sizes for each enclosure. The front side of each enclosure includes a blank label area for identifying custom circuits. Note that these housings are made from extruded bar stock, and as such, some minor cosmetic defects in the finished products are to be expected.

Each housing has two blank end plates with a Ø0.05" pilot bore through hole (EEA11) or dimple (all other housings) for custom connectors. Note that the dimple may be on the inner side of the end plate when the enclosure is shipped. We recommend using a step drill bit to machine a hole in the end plate; a standard, single-size drill bit may cause deformation in the plate. The end plates are easily removable and are held in place with 4-40 (EEA11) or M3 (all other housings) Phillips pan head screws.

Extra blank end plates or end plates with BNC or SMA connectors are available separately below. Extra M3 screws are also available below.

These BNC connectors feature a 75 Ω impedance. If mated to a 50 Ω BNC connector, they will introduce an impedance mismatch that may degrade performance.

Extra end plates are available for many of the housings sold above. Blank end plates and end plates with BNC or SMA connectors are available. See the table to the right for details.

The blank end plates have a Ø0.05" pilot bore dimple for custom connectors. We recommend using a step drill bit to machine a hole in the end plate; a standard, single-size drill bit may cause deformation in the plate. The blank end plates are also available in packs of 10.

End plates with BNC or SMA connectors have a pre-drilled hole for their respective connector type. The components require some assembly when shipped, as shown in the photo to the upper right. Both the BNC and SMA connectors included with these items are female connectors. For electrical specifications of the connectors, click on the red Docs icon () next to the item # below.

Aluminum Clamps, Post Mountable

These anodized aluminum clamps provide secure mounting for the rectangular electronics housings sold above. Four sizes of clamps are available, and each is designed to fit on one side of the housing; see the table below for compatibility. The clamp can snap onto the side of the appropriate housing and the flexure lock can be tightened using the 2 mm (5/64") hex locking screw on the side.

Each clamp has a #8 (M4) counterbore on the bottom; the ECM225 has three of these counterbores. The counterbores allow the clamps to be mounted on a Ø1/2" post or any surface with an 8-32 (M4) tap. The clamp must be mounted via the counterbore before the electronics housing is attached, as the counterbore will not be accessible once the housing is secured in the clamp.
